Lenovo USB-C to Ethernet Adapter – 4X90S91831

The Lenovo USB-C to Ethernet Adapter (4X90S91831) is a compact wired networking accessory designed to connect compatible USB-C enabled notebooks and systems to a traditional Ethernet network. It provides a practical alternative for systems that do not include an integrated RJ45 network port.

The adapter connects to the host through a USB Type-C interface and provides a full-size RJ45 Ethernet connector for wired networking. It supports Ethernet connectivity at Gigabit data rates according to the IEEE 802.3ab specification, as well as 100Mbps Ethernet according to IEEE 802.3.

Integrated LED indicators on the RJ45 connector provide convenient visual confirmation of network link and activity status. This makes it easy to identify whether the Ethernet connection is established and whether network traffic is being transmitted.

The Lenovo USB-C to Ethernet Adapter also supports useful enterprise networking functions. PXE boot and remote image loading are supported when the host system provides the required functionality. Wake-On-LAN from S3 is supported on compatible host systems, while MAC pass-through is available on selected ThinkPad notebook systems.

The USB-C connector is designed to be hot-pluggable and reversible, allowing the adapter to be inserted into a compatible USB-C port in either orientation. The host USB-C port must function as a Downstream Facing Port (DFP) for the adapter to operate correctly.

With its sleek black design, the adapter is suitable for mobile professionals, business users, IT administrators and organizations that need reliable wired network connectivity for USB-C equipped notebooks. It can also be useful for system imaging, network deployment and transferring large files over a wired network.

The adapter measures approximately 207 × 21 × 13mm and weighs approximately 24g. Its compact construction makes it easy to carry with a notebook or keep as part of an IT support kit.

The Lenovo USB-C to Ethernet Adapter 4X90S91831 is supplied with the adapter and publications and is backed by a 1-year Customer Replaceable Unit (CRU) warranty.
